Abstract

The invention provides a high-speed tool steel welding rod, relates to the field of welding, and is mainly used for meeting the requirements of procedures such as repairing of a high-speed steel mold and electroslag remelting of an electrode blank joint, namely the high-speed tool steel welding rod with the same material is needed. Specifically, the high-speed tool steel welding rod is prepared by the following steps of uniformly mixing the following powder in percentage by weight, then adding potassium sodium water glass accounting for 2.5%-3.5% of the total weight of the mixed powder, uniformly stirring, pressing and coating a high-speed steel core wire with the mixed powder, and drying; and the powder comprises the following components of, in parts by weight, 25 parts-30 parts of marble, 10 parts-12 parts of fluorite, 3 parts-5 parts of feldspar, 1 part-2 parts of high-carbon manganese, 1 part-2 parts of medium-carbon chromium, 2 parts-4 parts of ferrovanadium, 4 parts-6 parts of ferrotitanium, 10 parts-14 parts of titanium dioxide, 20 parts-25 parts of rutile, 4 parts-6 parts of zircon sand, 0.5 part-1.0 part of industrial silicon, 2 parts-3 parts of mica and 1 part-2 parts of sodium carbonate. The welding rod provided by the method is stable in electric arc during welding, less in splashing, complete in slag covering and good in high-current resistance.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a high-speed tool steel electrode and a preparation method thereof, which are mainly used for repairing high-speed steel molds and electroslag remelting electrode blank joints and other processes, that is, high-speed tools with the same material are required Steel welding rod. Background technique [0002] High-speed tool steel is widely used in industrial fields such as tool, cutting tool and model manufacturing. However, due to the constraints of its composition, structure and welding process, it is difficult to make it into welding rods for application. Therefore, there is no high-speed tool steel in the market. Application and sales of this product of tool steel welding rods. [0003] In actual production activities, the repair of some high-speed steel molds, and the electroslag remelting electrode billet joints and other processes require high-speed tool steel electrodes o...
